The competition dates back to 1939 when Shell Oil Company employees in the USA made a friendly wager over who could travel furthest on the same amount of fuel. Since then it has expanded to two more continents, includes many energy types and sparks passionate debate around the future of energy and mobility.

The competition is split into two classes or categories. The Prototype class focuses on maximum efficiency, while passenger comfort takes a back seat. The UrbanConcept class encourages more practical designs. Cars are also divided by energy type:

  • Internal combustion engine fuels include petrol, diesel, liquid fuel made from natural gas and ethanol.
  • In the electric mobility category, vehicles are powered by hydrogen fuel cells and lithium-based batteries.

Chalmers competed in the UrbanConcept class.


Chalmers has been taking part in the Shell EcoMarathon event for the past 4 years. we participate each year with an aim of creating a sustainable world : maximum efficiency with a minimum usage of resources.

The team 2018 consists of 18 members who are Master’s students at the Chalmers University of technology. The team is headed by Professor. Sven Andersson and will guide the team in this big journey. The team is divided into four different subgroups: Body and Drive train, Power Train, Electricals and Communications.


Body and drive train sub group deals a wide of aspects from tunnelling engine power to wheels, holding the vehicle up with rigid suspension, steering wheels, shaping up the body to aerodynamics and manufacturing of all the above components.


A Honda Gx35 CC internal combustion engine which runs on ethanol is used for the competition. The challenge is to identify and run the engine at its best efficiency and convert this mechanical energy to electrical energy by coupling it to an electric generator, which in turn will be stored in a super capacitor.


The responsibilities of the team include research and development of hybrid electric systems and components (motor, dc-dc converter, supercapacitor and their control systems), testing and analyzing parts utilizing actual car and bench testing. This will include hands-on assembly/disassembly of components, testing electro-mechanical systems and meeting with other departments to review technical issues, researching new technologies and proposing future works.


The team is responsible for the effective communication internally within the team and external communication. It is also responsible for Project  Web Management, Finance & Procurement, Single Point of External Contact and Marketing.
